Considering the educational services, the Brazilian Navy education aims to comply with continuous and progressive process of education, with own characteristics, which are constantly updated and improved based on some principles, such as guarantee of quality standard, continuous and progressive professionalisation, and integral and continuous evaluation. Therefore, this study aimed to assess the service quality of the training course at the Santa Catarina School of Sailor Apprentices, according to the students' perception. For this evaluation, the HEdPERF scale was used. Data collection was performed by using printed questionnaires and the sample consisted of 178 students enrolled in the sailor training course who voluntarily participated in the study. The instrument for data collection was validated by confirmatory component analysis by using the SmartPLS 3 software. Descriptive statistics and regression analysis were performed to assess the data with SPSS software. As a result, the study revealed that the respondents perceived the dimension "academic aspects" as having the highest quality, whereas the dimension "non-academic aspects" was perceived as having the lowest quality. Regression analysis showed that variables such as total monthly family income, education level and main motivation to enter the armed forces have a statistically significant relationship with certain items of the HEdPERF scale, which was adapted to the present study.
